The Calgary Fire Department is warning smokers to properly dispose of cigarettes and other smoking materials after a number of fires over the winter were determined to have been caused by the improper disposal of those materials.

“January 2019 saw crews respond to a number of fires that had a range of causes,” Carol Henke, a CFD public information officer, said in a statement. “Overall, the leading cause of residential fires in our city continues to be cooking left unattended, however, January saw a number of fires related to improper disposal of smoking material, a cause which also resulted in two fatality fires in December 2018.”
